IBC2022 Tech Papers: Trailblazing with 8K live VR at Beijing 2022 | Technical Papers

by admin

Overview

Previous services using 4K VR highlighted the potential of live VR video services, but fell short of the resolution needed for a great live sports experience. 4K resolution is not enough to meet the expectations of viewers who typically watch HD TV. Intel meets business needs with end-to-end solutions powered by Intel® Xeon® processors designed to deliver live 8K VR and 360-degree video experiences to billions of viewers worldwide . His one such solution was showcased at his 2022 Beijing Olympic Winter Games. There, his VR technology platform from Intel enabled the capture and production of the first-ever live 8K VR video broadcast fully produced for the Olympic Broadcast Service (OBS), which will then be made available. became. We own the rights of Broadcasters Worldwide (RHB).

Intel is a Worldwide Olympic Partner (TOP) providing VR technology platforms for the Olympic and Paralympic Games. Intel worked with OBS and other partners to create and deliver a pioneering 8K live VR experience using the latest processors, graphics cards, accelerators, cameras and delivery technology. An industry first, the collaboration streamed over 100 hours of the fully produced Beijing Olympic event in VR, complete with graphics and commentary. Six sports, including hockey, snowboarding and figure skating, were broadcast live in groundbreaking 8K resolution on both VR180 and VR360. User reviews have been great, and we believe a VR production of this quality meets the criteria to attract a broad general audience.

prologue

Live and cinematic VR video has gone through a roller coaster hype cycle over the past seven years. Expectations soared around 2016 for him, and there was a deep trough of disillusionment at the turn of the decade. Technology development continued during this hype cycle. VR cameras, headsets, and delivery technology have all been steadily improving. Technological advances and industry changes have sparked renewed interest in VR. This time, the technology exists to meet quality demands for an engaging and sticky user experience.

While previous live sports trials and services have proven its potential, 4K 360-degree resolution fell short of what was needed for a great VR experience. VR videos that span 180 or 360 degrees require very high source resolutions to meet the expectations of viewers who typically watch HD TV. You can now create and deliver pioneering 8K live VR experiences using the latest cameras, graphics cards and delivery technology. An industry first, he partnered with OBS to stream over 100 hours of the Beijing Olympics event in his breakthrough 8K quality in VR360 and VR180. Enabled by Intel and various third parties, OBS created and delivered events for his six sports: ice hockey, snowboarding, freestyle skiing, curling, short track, figure skating, and opening and closing ceremonies. All events were live-streamed to users in the US, China, and some users in Europe around the world.

The event was delivered to headsets, mobile devices and web players, and content included live events and on-demand features. This white paper focuses on workflows for live events experienced with VR headsets.

The production uses 5 VR180 cameras, and users can experience “VR Cast” by switching the director in a virtual suite environment. I also got access to one of her VR360 cameras and was completely immersed. The user could freely switch between the 180-degree feed and his 360-degree feed. The event was fully replayable immediately after the event, and the app also showed event highlights and special features, all in VR. As part of the experience, a virtual HD “jumbotron” displayed his TV broadcast, and a broadcast announcer joined the audio his feed.

The content was available to users of the “NBC Olympics VR by Xfinity” app in the US and CCTV’s Yangshipin app in China. Chinese users were also able to access webstreams on their mobile apps and browsers. App store reviews raved about the vast improvement in quality over similar his VR experiences in the past.
